php - Converting a multi-dimensional array into HTML form fields - how? -

-

i'm trying take multidimensional array , convert html form fields, this:

<input type="hidden" name="c_record[contact][0][name]" value="first last"> <input type="hidden" name="c_record[contact][0][date_submitted][date]" value="2010-01-01"> <input type="hidden" name="c_record[contact][0][date_submitted][hour]" value="10"> <input type="hidden" name="c_record[contact][0][date_submitted][min]" value="08"> <input type="hidden" name="c_record[contact][0][date_submitted][sec]" value="16"> <input type="hidden" name="c_record[contact][0][ip_address]" value="192.168.1.1">

here have far:

$fields = array(     'c_record' => array(         'contact' => array(             0 => array(                 'name' => 'first last',                 'date_submitted' => array(                     'date' => '2010-01-01',                     'hour' => '10',                     'min' => '08',                     'sec' => '16',                 ),                 'ip_address' => '192.168.1.1',             ),         ),     ), ); $form_html = array_to_fields($fields);  function array_to_fields($fields, $prefix = '') {     $form_html = '';      foreach ($fields $name => $value) {         if ( ! is_array($value)) {             if ( ! empty($prefix)) {                 $name = $prefix . '[' . $name . ']';             }             // generate hidden field             $form_html .= form::hidden($name, $value) . eol;         } else {             if ( ! empty($prefix)) {                 $prefix .= '[' . $name . ']';             } else {                 $prefix = $name;             }             $form_html .= array_to_fields($value, $prefix);         }     }      return $form_html; }

this works fine until ip_address, results in:

<input type="hidden" name="c_record[contact][0][date_submitted][ip_address]" value="192.168.1.1">

and additional fields after ip_address keep having previous field names added them.

how can make work?

you manhandle http_build_query service purpose, since naturally creates scrunched-together keys you're looking for. if wait until end urldecode keys , values, it's easy explode output, since = or & in key or value safely encoded.

function array_to_fields($array) {     $html = '';      $entries = explode('&', http_build_query($array));     foreach ($entries $entry) {         list($key, $value) = explode('=', $entry);         $html .= form::hidden(urldecode($key), urldecode($value)) . eol;     }      return $html; }

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
